For DVDs, there are two world wide standards that are followed for the video formatting of a DVD. NTSC and PAL are these two standards.
There are a few distinctions between PAL DVDs and NTSC DVDs.
NTSC DVDs have a frame rate of 29.97 frames per second and have a screen resolutions of 720 X 480. NTSC is the more widely used and accepted format for DVDs.
PAL DVDs have a frame rate of 25 frames per second and have a screen resolution of 720 X 576. All PAL DVD players can also play NTSC DVDs, however, the converse is not true. Most NTSC DVD players cannot play PAL DVDs.
It is for this reason that the best format choice to distribute your DVD project would be NTSC.
Most authoring platforms will author both NTSC and PAL DVDs, however, it is very difficult to convert one to the other once the format has been chosen. The reasoning behind this is that the vertical resolution of an NTSC to PAL comparison is 480 to 576, so if conversion was to occur between the two formats, there would be some vertical squeezing or stretching of the video depending on which way the conversion went. So you end up with people and objects that either look unusually tall or unusually short, or you will have to cut of some of the screen, all are un-natural looks.
So if you are deciding whether to create a project in PAL vs NTSC, your best bet is to shoot, edit and author all in the same format. Mixing format, example: shooting in PAL and editing and authoring in NTSC will still result in a skewed perspective.
So know your format, your target audience, and choose accordingly.
